LONDON/LISBON, May 19 (Reuters) - Portuguese insurer Fidelidade is exploring a potential stock market listing of its private healthcare subsidiary Luz Saude, six people familiar with the matter told Reuters. Luz Saude reported operating income of 599 million euros in 2022, a 10.6% jump from the year before, driven by growth in private healthcare services. They come after Fidelidade acquired the remaining 49% of Luz Saude it did not already own from parent Fosun in September. An IPO would mark a return of Luz Saude to the stock market after the healthcare group stopped trading on Euronext Lisbon in 2018. It could also awaken Europe's IPO market, after activity levels plunged last year on the back of soaring interest rates and economic uncertainty.
